Installing DataStax Community on any Linux-based platform
Install on all Linux-based platforms, including Mac OSX and platforms without package support, or if you do not have or want a root installation.
Use these steps to install Cassandra on all Linux-based platforms using a binary tarball.
- The latest version of Oracle Java SE Runtime Environment (JRE) 6 or 7. See Installing the JRE.
- Java Native Access (JNA) is required for production installations. See Installing the JNA.
- Python 2.6+ (needed if installing OpsCenter).
- If you are using Ubuntu 10.04 LTS, you must update to JNA 3.4, as described in Installing the JNA using the binary tarball.
- If you are using an older RHEL-based Linux distribution, such as CentOS-5, you may see the following error: GLIBCXX_3.4.9 not found. You must replace the Snappy compression/decompression library (snappy-java-1.0.5.jar) with the snappy-java-184.108.40.206.jar.
The binary tarball runs as a stand-alone process.
In a terminal window:
Check which version of Java is installed by running the following
java -versionUse the latest version of Java 6 or 7 on all nodes.
Download the latest DataStax Community tarball:
$ curl -OL http://downloads.datastax.com/community/dsc-1.2.tar.gzYou can also download from Planet Cassandra.
Unpack the distribution:
$ tar -xvzf dsc-cassandra-1.2.x-bin.tar.gz $ rm *.tar.gz
Go to the install directory:
By default, Cassandra installs files into the
/var/log/cassandra directories. If you do not have root
access to the default directories, ensure you have write access:
$ sudo mkdir /var/lib/cassandra $ sudo mkdir /var/log/cassandra $ sudo chown -R $USER: $GROUP /var/lib/cassandra $ sudo chown -R $USER: $GROUP /var/log/cassandra
